1. Enter Pairing mode:
To enter pairing mode, turn on PTT, press PTT button for 10 seconds then release.
2. Change PTT Button pairing to a new phone:
1. In phone A, forget(un-pair) the PTT in “Setting” -> “Bluetooth”
2. Turn on PTT, make sure it is NOT connected to any phone.
3. Press PTT button for 10 seconds then release (like in 1).
4. Phone B now can scan the PTT button, pair and connect the PTT.
Note:

Bluetooth is OFF.
2. If accidently press PTT button for 10 seconds in non-connected mode, the pairing info will be erased. Please run 1 or 2 to re-connect the PTT and
phone.
Trouble shooting:
1.Scenario: If turn Bluetooth OFF then ON in system’s setting, the link between ESChat and PTT will lost but ESChat is not able to detect this, PTT stop working.
Fix: Quit ESChat and return to desktop, then switch PTT OFF and ON and back to ESChat, now the connection will established and PTT will work again.
Note: If system Bluetooth has been OFF and ON, PTT device needs do the same, i.e. switch OFF and ON the PTT, in order to notify App the connection is re-
established.
2.Scenario Multiple BLE devices connected to the phone: suppose there’re two BLE devices, device A is other PTT and device B is Blu-PTT. Now turn off phone’s
Bluetooth and ON again, although both devices will re-connected, but Blu-PTT will not function again.
Fix: “Forget” all BLE PTT devices (include Blu-PTT) and pair/connect ONLY with Blu-PTT and try again.
3.Scenario More than one PoC Apps are running: some Apps(such as Zello) will connect Blu-PTT automatically before Blu-PTT can connect to the phone, at this
moment the phone(under Setting-> Bluetooth) will not able to connect Blu-PTT.
Fix: go Setting-> Application -> Application manager to “Force Stop” the App(such as Zello) which will issue the connection with Blu-PTT, and try again.
Note: Blu-PTT supports multiple Apps, some Apps are more “aggressive” than ESChat and will unexpectedly taking the control of the PTT button.
